Interaction Analysis of Girder Bridges and Traffic System subjected to Earthquakes

Due to the limitation on current seismic forecasting techniques, there is usually a very short warning time for traffic to be evacuated from a bridge before seismic strikes. As a result, it is very likely that normal traffic still remain on the bridge when seismic occurs. Bridge seismic analysis typically does not consider the presence of traffic and the dynamic interactions. In recent years, some studies have been carried out on the bridge seismic performance when traffic is included and existing studies suggest that traffic has some influence on bridge seismic performance, which should not be neglected. In addition to the bridge safety concern, the moving vehicles may also experience some safety risks under seismic. However, most of existing studies considered one or several individual vehicles without appropriate modeling of dynamic interactions. In order to evaluate the performance of the bridge and traffic system, the dynamic performance of the coupled bridge and traffic system needs to be rationally predicted.
